Pure500 turbo, all supporting mods, what tune do i run?

mattyfargo · Yesterday, 01:53 PM

My 2011 e90 n55 has 120k miles. It currently has FBO (5inch intercooler, catless downpipe and muffler delete(Still has secondary cats), aluminum charge pipe, cold air intake, and currently running MHD 2+) Manual transmission

Ive purchased a pure500 turbo, ACL Rod bearings, upgraded coil packs, step 1 colder NGK spark plugs, Stage 1 LPFP from Fuel-It, and a Spool 150 Stage 1 HPFP. I may get a oil catch can, but i've read their not entirely necessary. I am a technician for BMW (almost 2 years experience and 2 years of schooling) and plan on installing them soon.

This is my street car, and of course I must pass my yearly emissions inspection.

I dont have any experience with tuning aside from flashing my car MHD with a tablet, and my biggest concern is figuring out the tuning situation.

My goal is 500whp or around there, and have read that n55 rods can handle that, but I am reinforcing the bearings just to be safe (Never been replaced and still no issues)

How should i get it tuned? Do tuning companys just throw my car on the dyno and use their own platform and ECU to configure boost pressure and A/F ratio? I heard that you can send your logs to MHD and they can make you a custom map? How reliable is that? Can they really just make you a tune without dynoing the car? I live in Massachusetts and am willing to drive just about anywhere to have my car tuned properly after the mods are installed.

I also have stage 2 nostrum injectors that im not sure i want to install. I read they must be tuned for the vehicle, but if I flash it back to stock for my yearly inspection, will the car not run properly with the Stg2 injectors? Will i have to swap the injectors yearly?

That was a lot but let me know if you can answer any of those questions, thanks

In the sense that he wants to know the outcome. I am also curious about the results, as I want to do something similar.
Tuner wise, you can contact David Shoup, I heard he is very professional. You can book a dyno day in your area so you can test it also on the dyno
